The Powerline Communications (PLC) technology allows data
transmission through electrical wires. Thus the electrical wiring will represent
a data transmission channel conformable to the physical layer of the open
system interconnection (OSI) model. In this work, the specifications of the Iraqi
electrical network were used to model a high-voltage transmission line using a
transmission (ABCD) matrix and use it as a communication channel for
transmitting data within a narrow band (30-500). The transfer function of the
suggested model was derived and its performance analysis was performed to
evaluate the Line length effect, load impedance ZL and the source impedance ZS
on the channel frequency response. This analysis was done with the help of
Matlab16a simulator program.
